    1. Background

      On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS (62

      FR 38856) and a new PM2.5NAAQS (62 FR 38652). The revised ozone NAAQS is based on 8-hour average concentrations. The 8-hour averaging period replaced the previous 1-hour averaging period, and the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm. The new PM2.5NAAQS established a health-based

      PM2.5standard of 15.0 micrograms per cubic meter ([mu]g/ m\3\) based on a 3-year average of annual mean PM2.5 concentrations, and a 24-hour standard of 65[mu]g/m\3\ based on a 3- year average of the 98th percentile of 24-hour concentrations. EPA strengthened the 24-hour PM2.5NAAQS from 65[mu]g/m\3\ to 35[mu]g/m\3\ on October 17, 2006 (71 FR 61144).

      Section 110(a) of the CAA requires States to submit State

      Implementation Plans (SIPs) that provide for the implementation, maintenance, and enforcement of new or revised NAAQS within three years following the promulgation of such NAAQS. In March of 2004,

      Earthjustice initiated a lawsuit against EPA for failure to take action against States that had not made SIP submissions to meet the requirements of sections 110(a)(1) and (2) for the 1997 8-hour ozone and PM2.5NAAQS, i.e., failure to make a ``finding of failure to submit the required SIP 110(a) SIP elements.'' On March 10, 2005, EPA entered into a Consent Decree with Earthjustice that obligated EPA to make official findings in accordance with section 110(k)(1) of the CAA as to whether States have made required complete

      SIP submissions, pursuant to sections 110(a)(1) and (2), by December 15, 2007 for the 1997 8-hour ozone NAAQS, and by October 5, 2008 for the 1997 PM2.5NAAQS. EPA made such findings for the 1997 8- hour ozone NAAQS on March 27, 2008 (73 FR 16205) and on October 22, 2008, (73 FR 62902) for the 1997 PM2.5NAAQS. These completeness findings did not include findings relating to: (1) Section 110(a)(2)(C) to the extent that such subsection refers to a permit program as required by part D Title I of the CAA; (2) section 110(a)(2)(I); and (3) section 110(a)(2)(D)(i), which has been addressed by a separate finding issued by EPA on April 25, 2005 (70 FR 21147).

      Therefore this action does not cover these specific elements.

    2. Summary of State Submittals

      Delaware provided multiple submittals to satisfy section 110(a)(2) requirements that are the subject of this proposed action for the 1997 8-hour ozone NAAQS, and the 1997 and 2006 PM2.5NAAQS. The submittals shown in Table 1 addressed the infrastructure elements, or portions thereof, identified in section 110(a)(2) that EPA is proposing to approve.

      EPA has analyzed the above identified submissions and is proposing to make a determination that such submittals meet the requirements of section 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K),

      (L), and (M), or portions thereof. A detailed summary of EPA's review and rationale for approving Delaware's submittals may be found in the

      Technical Support Document (TSD) for this action, which is available on line at, Docket number EPA-R03-OAR-2010- 0158.

    3. Proposed Action

      EPA is proposing to approve Delaware's submittals that provide the basic program elements specified in the CAA sections 110(a)(2)(A), (B),

      (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M), or portions thereof, necessary to implement, maintain, and enforce the 1997 8-hour ozone and PM2.5NAAQS, and the 2006 PM2.5NAAQS.

      EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

    4. Statutory and Executive Order Reviews

      Under the Clean Air Act, the Administrator is required to approve a

      SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).

      Thus, in reviewing SIP submissions, EPA's role is to approve State choices, provided that they meet the criteria of the Clean Air Act.

      Accordingly, this action merely proposes to approve State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this proposed action:

      Is not a ``significant regulatory action'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

      Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

      Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory

      Flexibility Act (5 U.S.C. 601 et seq.);

      Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded

      Mandates Reform Act of 1995 (Pub. L. 104-4);

      Does not have Federalism implications as specified in

      Executive Order 13132 (64 FR 43255, August 10, 1999);

      Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

      Is not a significant regulatory action subject to

      Executive Order 13211 (66 FR 28355, May 22, 2001);

      Is not subject to requirements of Section 12(d) of the

      National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and

      Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under

      Executive Order 12898 (59 FR 7629, February 16, 1994).

      In addition, this proposed rule, pertaining to Delaware's section 110(a)(2) infrastructure requirements for the 1997 8-hour ozone and

      PM2.5NAAQS, and the 2006 PM2.5NAAQS does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in

      Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
